Abstract
The utility model provides a connection type radiator, comprising an insert base and at least two long ribs, wherein a short rib is arranged between every two long ribs, tree-shaped twigs are arranged on the long ribs, and veins are marked on the twigs. The tress-shaped electronic radiator has the advantages that under the condition of not changing the volume and the weight, the radiation area is continuously enlarged, and thereby the radiation effect is more obvious.
Description
Technical field
The utility model belongs to electronic technology field, relates to a kind of tree-like electronic radiation device.
Background technology
The fast development of electronic applications is had higher requirement to radiator.According to hot transfer principle as can be known, heat transmission mainly contains three kinds of modes, i.e. conduction, radiation, convection current.Heat conducting formula is Q=K*A* Δ T/ Δ L, and wherein, the K coefficient of heat conduction, A are heat transfer area, and Δ T/ Δ L is the temperature difference in the unit distance; Thermal-radiating formula is: Q=H*A* Δ T, and wherein, H is a coefficient of heat convection value, and A is the effective area of convection current, and Δ T is the temperature difference; The formula of thermal convection is: Q=E*S*F* Δ (Ta-Tb), and wherein, E is the heat emissivity coefficient of surface area, S is a surface area.No matter be that a kind of radiating mode as can be seen, enlarging area of dissipation all is valid approach.As the patent No. is 01247684.6 utility model patent, and a kind of electronic radiation device of electronic element radiating is provided, and it comprises heat transfer substrate and the radiator shutter that is fixed with one with it; And radiator shutter not only is distributed on the heat transfer substrate plate face, also extend at least one side of heat transfer substrate, form the side radiator shutter, even the upper side of its side radiator shutter can exceed the upper surface of heat transfer substrate, therefore, radiator shutter is distributed in around the heat transfer substrate to greatest extent, and it is maximum that its area of dissipation reaches, and it is the highest that radiating efficiency also reaches.And, further improved its radiating efficiency owing to also be provided with the heat absorption panel on the heat transfer substrate upper surface.But along with continuing to increase of whole set equipment, demand to the area of dissipation of radiator also continues to increase, if, then can play the effect of heat radiation more so can under the situation of the volume and weight that does not change original radiator, continue to increase the area of dissipation of radiator.
The utility model content
In order to overcome above-mentioned electronic radiation device can not continue to increase area of dissipation on the basis of the volume and weight of original radiator defective, the utility model provides a kind of tree-like electronic radiation device, the radiator fin is made the crotch shape, texture is marked on the surface again, area of dissipation is under the situation that does not change volume and weight, also can continue to increase, radiating effect can be more obvious.
The utility model is realized by following scheme: a kind of tree-like electronic radiation device, comprise an inserted sheet base and at least two long fins, long fin equidistantly is welded on the inserted sheet base, short fin of welding is on the inserted sheet base between per two long fins, long fin is provided with tree-like branch, and drawing on the branch has texture.
Description of drawings
Fig. 1 is tree-like electronic radiation device structural representation.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail, but not as to qualification of the present utility model.
As shown in Figure 1, a kind of tree-like electronic radiation device, a kind of tree-like electronic radiation device, comprise an inserted sheet base 1 and at least two long fins 2, long fin 2 equidistantly is welded on the inserted sheet base 1, and a short fin 4 is arranged between per two long fins 2, and short fin 4 also is welded on the inserted sheet base 1, long fin 2 is provided with tree-like branch 3, and drawing on the branch 3 has texture.
